Title

(EN) DIGITAL TRIMMING OF ANALOG COMPONENTS USING NON-VOLATILE MEMORY

(FR) DIGITAL TRIMMING OF ANALOG COMPONENTS USING NON-VOLATILE MEMORY

Abstract

(EN) An analog electronic component, includes input and output pins, analog devices and non-volatile fuses. The analog devices are operative to perform analog signal processing on signals received via at least one input pin and to output processed signals on at least one output pin. The analog devices include adjustable elements. The non-volatile fuses are coupled to the adjustable processing elements and are electrically programmable via at least some of the input pins. Programming the non-volatile fuses adjusts the adjustable elements to alter characteristics of the analog signal processing.
